1. A tooth-coating composition comprising
a) whiteness-imparting particulate material comprising white crystalline hydroxyapatite, b) an acrylate co-polymer consisting of monomers of t-butyl acrylate, ethyl acrylate, and methacrylic acid, c) one or more non-acrylate polymers selected from the group consisting of carboxymethylcellulose acetate butyrate, cellulose acetate butyrate, ethyl cellulose, marine colloids, chitosan, polyvinylpyrrolidone/vinyl acetate copolymer, and mixtures thereof, wherein said acrylate co-polymer is present at a concentration of from 60% to 99% by weight of the composition. |
